如何使用android在webview中播放视频？

Answer 1

首先关心编码。这是一篇带有工作示例的文章以及一些针对 Android webkit 进行视频编码的指南。

然后......当我不得不面对这个问题时，我必须进行一些研究并找到一些有用的答案。基本上你必须像本机浏览器一样打开视频

public class InredisChromeClient extends WebChromeClient implements OnCompletionListener, OnErrorListener {
    private InterfazWebInredis interfazWeb; // Use Your WebView instance instead

    private VideoView mCustomVideoView;

    private LinearLayout mContentView;
    private FrameLayout mCustomViewContainer;
    private WebChromeClient.CustomViewCallback mCustomViewCallback;
    private LinearLayout mErrorConsoleContainer;
    static final FrameLayout.LayoutParams COVER_SCREEN_GRAVITY_CENTER = new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT,
            ViewGroup.LayoutParams.FILL_PARENT, Gravity.CENTER);

    public InredisChromeClient(InterfazWebInredis iwi) {
        super();
        this.interfazWeb = iwi;
    }

    public void onShowCustomView(View view, CustomViewCallback callback) {
        // super.onShowCustomView(view, callback);
        if (view instanceof FrameLayout) {
            mCustomViewContainer = (FrameLayout) view;
            mCustomViewCallback = callback;
            mContentView = (LinearLayout) interfazWeb.findViewById(R.id.mainContainer);
            if (mCustomViewContainer.getFocusedChild() instanceof VideoView) {
                mCustomVideoView = (VideoView) mCustomViewContainer.getFocusedChild();
                // frame.removeView(video);
                mContentView.setVisibility(View.GONE);
                mCustomViewContainer.setVisibility(View.VISIBLE);
                interfazWeb.setContentView(mCustomViewContainer);
                mCustomVideoView.setOnCompletionListener(this);
                mCustomVideoView.setOnErrorListener(this);
                mCustomVideoView.start();
            }
        }
    }

    public void onHideCustomView() {
        if (mCustomVideoView == null)
            return;
        // Hide the custom view.
        mCustomVideoView.setVisibility(View.GONE);
        // Remove the custom view from its container.
        mCustomViewContainer.removeView(mCustomVideoView);
        mCustomVideoView = null;
        mCustomViewContainer.setVisibility(View.GONE);
        mCustomViewCallback.onCustomViewHidden();
        // Show the content view.
        mContentView.setVisibility(View.VISIBLE);
    }

    @Override
    public void onCompletion(MediaPlayer mp) {
        mp.stop();
        mCustomViewContainer.setVisibility(View.GONE);
        onHideCustomView();
        interfazWeb.setContentView(mContentView);
    }

    @Override
    public boolean onError(MediaPlayer mp, int what, int extra) {
        interfazWeb.setContentView(R.layout.main);
        return true;
    }
}

所以，这段代码的灵感来自于浏览器的android项目源代码。

好吧，这个行为是全屏打开视频。我不知道是否可以在网页内自己的框架中播放视频。但这个解决方案对我有用，我希望对你也有用。

这应该可以在您已经使用的 2.x 版本中运行。但doc说当浏览器全屏时该标签将起作用。

您的网络视图也有可能支持它，但它需要全屏。 试试这个。 （不过我还没试过）

编辑：要使视图全屏显示，您可以尝试以下操作：

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
